We introduce a simple primitive called Augmented Broadcast Encryption (ABE) that is sufficient for constructing broadcast encryption, traitor-tracing, and trace-and-revoke systems...
Abstract. Side-channel attacks are a very powerful cryptanalytic technique. Li and Gu [ProvSec’07] proposed an approach against side-channel attacks, which states that a symmetri...
Abstract. In a related-key attack, the adversary is allowed to transform the secret key and request encryptions of plaintexts under the transformed key. This paper studies the secu...
Self-Synchronizing Stream Ciphers (SSSC) are a particular class of symmetric encryption algorithms, such that the resynchronization is automatic, in case of error during the transm...
Abstract. In this paper we present a general framework for constructing efficient multicast cryptosystems with provable security and show that a line of previous work on multicast ...
